Magnetic structure of transition region blinkers

Analysis of the photospheric magnetic field has shown that the majority of blinkers, small-scale intensity enhancements seen in the transition region, occur above single fragments. We investigate the relationship between the strength of these single magnetic fragments or the ratio of any mixed magnetic fields beneath blinkers and blinker characteristics. In all cases, no correlation is found between the strength of the magnetic field and the blinker properties. We suggest, therefore, that blinkers are not caused by reconnection and that other mechanisms should be explored further.
